Rocker Boards have just one plane of instability (side to side or front to back motion), which make them great for beginners.
They offer an unstable surface designed to facilitate balance and proprioceptive training and automatic postural reactions. The Rocker Board is ideal for rehab, post-rehab conditioning, and other fitness applications.
